IMPROVEMENT IN sona-FUNTAINS.

The Schedule referred to in these Letters Patent and -making part of the same.

Fountains; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference Abeing had to the accompanying drawings, forming part of this specification.

This invention is an improvement on the soda-fountain patented by F. J. Chapman on the 5th day of September, 1865, and numbered 49,719, and relates to a componnd-lever arrangement-otthe treadles by which the plunger lof the pump is operated.

It also relates to the combination of the levertreadles with the'fountain 5' also, the manner of combining the levers, ltube, and plunger with the crooked connecting-rod, by passing the said rod down betweenv the inner and outer walls of the refrigerator.

Figure 1 is a vertical section of the `fountain and frame-work.v y

Figure 2 is a plan View of the bottom.

Similar letters of reference indicate corresponding parts. v

A is the cylindrical chamber of the fountain; and

F, an outery cylinder or casing.

Between these casings is placed the non-conductin g material E.

C is the pump-chamber, in which. is the plunger b.

Tothe chamber C is attached the ejection-tube d.

c is the pump-rod, connecting with the plunger at lone end, and at the other with the treadle (d, the said rod being doubled on itself', in the manner shown, so that it may pass over the side Vof" the chamber A.

B is the cap of the fountain, attached to the cover of the same by the screws 'm m, so thatit may be used as a counter and receptacle for glasseswhile on the fountain, or may be removed, if it is desired to place the same under a counter or table.

This cap is provided with a door, D, which is fastcned by the button or catch e.

In the hollow base of the fountain are the treadles al a2.

The treadle al makes the down stroke of the plunger b, and is attached to the lower end of the pumprod c by the .screw l, the rear end of the treadle being pivoted on the screw k, thus forming a lever ofthe third class.

The treadle a2 isf. provided with a sleeve, s, which slips looselyon the bar of the other treadle, as shown.

This treadle is pivoted on the fulcrum-pin or screw n, thus forming a lever of the tirst class, and operating, when pressed-down, to raise the lever or-treadle a, and, through it, the plunger b ot' the pump.

The treadles are provided with plates for the foot, and work in slots in the base of the fountain,l being stopped bythe check-plate o, all of which is clearly shown'in fig. 2. y

The operation isvery simple:

Nhen the treadle a* is pressed down by the foot, the Vplunger' b of the pump is forced down. This pressure also. raises the treadle ai, by retson of its operating on the rear end ofthe said treadle, beyond its fulcrum n.

A downward pressure on the treadle raises the,

plunger b of the pump, through the medium of thev treadle a, said treadle being lifted by the sleeve s, attached to the rear end of the bar of the lever a2."

Thus, a downwardprcssure,of the foot on the 1evers, alternately, is all that is required to operate the plunger of' the pump C, either up'or down.

Having thus described my invention, What I claim as new, and desire to secure by Letters Paten t, is-

The-combination, herein shown, of the vtreadles al a, with the bent pump-rod c, tube y, and pump O, of a soda-fountain, when the said parts are arranged to operatevsubstautially in the manner and for the purposes as set forth.
